Dual-Station Motorized Crocking Tester

The Dual-Station Motorized Crocking Tester is designed to evaluate the color fastness of textiles and leather to rubbing. This dual-station motorized crocking tester determines the degree of color transfer from dyed materials onto a standard white cotton cloth under dry or wet rubbing conditions, providing reliable assessment of color fastness performance.

Application

(1) Dyed fabrics such as cotton, polyester, and blended textiles

(2) Leather materials used in footwear, garments, and upholstery

(3) Printed and coated fabrics for apparel and home textiles

(4) Automotive interior materials such as seat covers and trims

(5) Quality control testing in textile and leather manufacturing

Standards

(1) ISO 105 (Textiles – Tests for colour fastness)

(2) ASTM D2054 (Color fastness to crocking)

(3) JIS L0849 (Test method for color fastness to rubbing)

(4) GB/T 3920 (Textiles – Tests for color fastness to rubbing)
